Title:
MANUFACTURING METHOD FOR OLED PANEL AND OLED PANEL
Document Type and Number:
WIPO Patent Application WO/2019/071711
Kind Code:
A1
Abstract:
A manufacturing method for an organic light emitting display (OLED) panel and an OLED panel. The manufacturing method for an OLED panel comprises: on a thin film transistor (TFT) substrate (100), manufacturing an anode (310) that is connected to a source (121) of a TFT (120), and a lap joint electrode (320) that is connected to an auxiliary electrode (130); manufacturing multiple metal protrusions (400) that are provided with sharp corners on the lap joint electrode (320) such that the positions of an electron transmission layer (640) and an electron injection layer (650) corresponding to the sharp corners of the metal protrusions (400) have a thinner film thickness after sequentially forming entire surfaces of the electron transmission layer (640), the electron injection layer (650) and a cathode (700) during a subsequent process; burning off the positions of the electron transmission layer (640) and the electron injection layer (650) corresponding to the sharp corners of the metal protrusions (400) due to a large impedance at the sharp corners of the metal protrusions (400) after applying a voltage to the auxiliary electrode (130) or the lap joint electrode (320), thereby causing the cathode (700) and the auxiliary electrode (130) to be connected such that the OLED panel may input signals to the cathode (700) by means of the auxiliary electrode (130) during display, thus effectively improving the problem wherein display by the OLED panel is uneven due to the IR drop of the cathode (400).
